Health outlet Verywell Health outlines five ways fitness trackers can help catch early signs of health issues as people age. The piece suggests wearable devices that monitor metrics like heart rate and sleep patterns may alert users to changes worth discussing with a doctor. Wearables are increasingly seen as a tool for preventive health monitoring in older adults.

The Wildlife Conservation Society is highlighting efforts to close what it calls the world's wildlife health blind spot, arguing that weak monitoring of disease in wild animal populations leaves both biodiversity and human health exposed. The organisation is calling for stronger investment in wildlife health surveillance as part of global conservation and pandemic-prevention work.

Wyoming Game and Fish is asking hunters to avoid shooting animals wearing research collars. The department's request, reported by the Billings Gazette, is aimed at protecting GPS-collared elk, deer, moose and other wildlife whose collars provide scientists with vital data on migration patterns and population health. Hunters are being reminded that collared animals can still be legally taken in some cases, but sparing them helps ongoing research efforts.

The World Health Organization is hosting a webinar for the UN International Day of Older Persons 2026, themed 'The Age of Longevity: Rethinking Systems for Longer Lives'. The event focuses on how health, social and economic systems must adapt as populations worldwide live longer. Details on speakers and registration are expected from the WHO in the run-up to the day.

The US Bureau of Land Management has begun management actions aimed at protecting the Sulphur wild horse herd and the health of its rangeland, citing overpopulation as the driving concern. The agency says the measures are intended to keep herd numbers in balance with available forage and water. Wild horse management decisions by the BLM routinely draw attention from animal welfare advocates, ranchers and public lands groups, who often disagree over how population levels should be controlled.

Robert F. Kennedy Jr. has announced $12 million in funding for programs in Houston addressing homelessness, addiction and mental health. The announcement, reported by KHOU, directs federal support toward services in a city that has faced growing pressure on its homeless population and related health needs. Details on how the money will be allocated across the three areas were not immediately specified.

The University of Pennsylvania is highlighting the work of those supporting student mental health on campus, examining how staff and clinicians are responding to growing demand for psychological support among students. The piece spotlights frontline efforts to address wellbeing at a time when colleges worldwide are facing rising rates of anxiety, depression and other mental health challenges among their student populations.

The Centers for Disease Control and Prevention have published the public-use files from the 2025 National Health Interview Survey, making the nation's largest in-person household health survey data available to researchers, policymakers and the public. The release allows analysis of health status, insurance coverage, access to care and health behaviours across the US population for the year.

Researchers at the Centre for Population Change, including Athina Vlachantoni, Saddaf Naaz Akhtar, Spela Mocnik and Yuanyuan Yin, have published a new paper using Understanding Society data. The study assesses how ethnicity and gender, alongside demographic, health, socioeconomic and subjective wellbeing factors, shape outcomes. The centre announced the publication to its followers.

The Wyoming Game and Fish Department is tracking a seasonal outbreak of epizootic hemorrhagic disease affecting white-tailed deer and pronghorn in the Casper region. The disease, spread by biting midges, typically flares up in late summer and can cause significant die-offs. Officials are monitoring affected herds and asking the public to report sightings of sick or dead animals.

A peer-reviewed study published in the European Journal of Psychotraumatology analysed data from a nationally representative survey of civilians living in government-controlled regions of Ukraine. It offers new estimates of post-traumatic stress disorder prevalence, adding to the picture of the war's mental health toll on the population.

The European Observatory on Health Systems and Policies argues that Europe's most transformative health innovation is social rather than technological. The claim directs attention to social innovations—such as community-based care and new ways of organising health services—as the real drivers of change in European health systems, instead of new drugs, devices or digital tools.

New demographic analysis highlights that while Europe remains the world's oldest region by median age, Latin America's population is aging at a much faster pace. The finding draws attention to how quickly fertility declines and rising life expectancy are transforming societies that were until recently considered young, raising questions about pension systems and health care across the region.

A new report suggests that whether older women drink tea or coffee could influence their risk of developing osteoporosis, the condition that weakens bones. The finding, highlighted by ScienceAlert, adds to ongoing research into how everyday dietary habits shape bone health in later life. Details of the underlying study, including its size and methods, were not provided.

Researchers in the Wilmington, North Carolina area spent three nights field-surveying bats, working after dark to locate and monitor the animals across the region. The work points to ongoing efforts to understand local bat populations, which matter for insect control and ecosystem health, and the unusual nighttime effort is drawing local attention.

Oklahoma wildlife officials have confirmed the state's sixth case of chronic wasting disease in a deer, a fatal neurological illness affecting deer, elk and moose. The news is drawing attention from hunters and conservationists concerned about the disease's spread across the region and its potential impact on deer populations and hunting seasons.

Public health experts are highlighting how population-level strategies can reduce suicide rates. The approach focuses on prevention beyond individual treatment, including crisis support, means restriction, and community programmes. The topic comes as suicide remains a leading cause of death worldwide, prompting renewed discussion about systemic prevention measures.

Researchers have published a high-resolution genome-wide association study of roughly 600,000 people with East Asian ancestry, aiming to break down why type 2 diabetes rates and risk factors differ between populations. The work, appearing in Nature, identifies ancestry-specific genetic contributions to diabetes risk and may help explain the higher disease burden seen in East Asian populations compared with other groups.

The American Medical Association is highlighting what age-friendly care involves for older adults, focusing on how health systems can tailor treatment to the needs and priorities of aging patients. The approach emphasizes respecting older adults' goals, mobility, mental health and medication needs rather than treating age alone as a medical problem.

Nutraceutical Business Review highlights recent scientific research on probiotics and healthy ageing, covering findings that link gut microbiome health to longevity and quality of life in older adults. The piece points to growing industry and consumer interest in probiotic supplements as part of ageing well, though it reports no specific new study or product launch.

The EU's climate agency reports that nearly 40% of the world's population was exposed to harmful ozone pollution in 2026. The finding highlights the growing reach of ground-level ozone, a pollutant linked to respiratory illness and premature deaths. The assessment is drawing attention to air quality as a major global health and climate concern.

Astrana Health has filed a notification with the Securities and Exchange Commission disclosing a social engineering incident. The healthcare company, which manages care for large patient populations, informed investors and regulators of the event as required under disclosure rules. Social engineering attacks typically involve manipulating staff into revealing credentials or sensitive data, and healthcare firms are frequent targets. Details on the scope of the breach and any patient data exposure have not yet been made public.
